Benefits of technology
The present invention provides a navigation information device and method that can easily understand the surroundings of a ship and improve visibility using sonar detection. The device includes two screens that show information about the ship and nearby fish schools or other targets, making it easy to see the situation around the ship. This improves the chances of safely navigating through the water.
Problems solved by technology
However, since an area to be detected by the sonar is, for example, an area having a radius of about 5 km around the ship itself, and the display area of the detection result by the sonar is small relative to an entire chart, the detection result is difficult to be confirmed on a display screen.
On the other hand, there is a problem that a chart of a wide area cannot be displayed on a screen in which the area to be detected by the sonar is largely displayed, and the surrounding situation of the own ship cannot be sufficiently grasped.

Embodiment Construction
[0018]Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and the description thereof will not be repeated. At least some of the embodiments described below may be optionally combined.
[0019]FIG. 1 shows a configuration of a navigation information system 201 according to the embodiment of the present invention.
[0020]Referring to FIG. 1, the navigation information system 201 includes a navigation information device 101, a monitor 102, a radar 103, a sonar 104, and an external device 105. The navigation information system 201 is mounted on a ship. Hereinafter, a ship equipped with the navigation information system 201 is also referred to as an “own ship”.
[0021]The radar 103 transmits a radio wave, receives a reflected wave of the transmitted radio wave from a target, and detects the target, such as another ship or the like, existing around the own shi...

The purpose is to provide a navigation information device and a navigation information processing method capable of excellently grasping a surrounding situation of own ship and improving a visibility of a detection result by a sonar. The navigation information device is provided with a surrounding information generating module for generating surrounding information around the ship itself, a sonar information generating module for generating sonar information indicating the detection result by the sonar, and a display control module for performing control for enlarging one display area of a surrounding screen on which the surrounding information is displayed and a sonar screen on which the sonar information is displayed and reducing the other display area, as compared with corresponding display area before satisfying the predetermined condition, when the predetermined condition is satisfied.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 U.S.C. § 119 to Japanese Patent Application No. 2020-045938, which was filed on Mar. 17, 2020, the entire disclosure of which is hereby incorporated by reference.BACKGROUND OF THE INVENTIONTechnical Field[0002]To provide a navigation information device and a navigation information processing method.Description of the Related Art[0003]Conventionally, a technique has been developed in which a detection result of a target such as a fish school by a sonar mounted on a ship is superimposed on a chart screen showing a surrounding situation of an own ship.[0004]However, since an area to be detected by the sonar is, for example, an area having a radius of about 5 km around the ship itself, and the display area of the detection result by the sonar is small relative to an entire chart, the detection result is difficult to be confirmed on a display screen.[0005]On the other hand, there is a problem that a cha...
